Can't expand headers within `<>`

[ishandutta2007]

I believe the code is designed to expand headers within "" only. For example when I am trying to amalgamate this code primecount api, since in #include <primecount.hpp> the header name primecount.hpp is enclosed by <> it fails to pull in the required code. Ideally we should use a lookup table to check if a header is native c++ header or not . Dont you think so? Please do update if you can get quom to work with the above repo.

PS: This ticket has nothing to do with my other ticket. Now I am on macOS and I dont have that issue here.
